I am an avid reader and we would have hundreds of books here in my home. I am also passionate about good quality books, in particular for children. I read classics, literary fiction and mainstream fiction. I prefer to read good quality literature for myself and to my children but not everything has to be the best book ever written to be enjoyed and loved. I'm sure there are books I loved as a kid that were far from good literature but the love of reading has stayed with my always and I would rather people read their children "junk" (to use your word) and have them love books because they had favourites as a child, than not have had that connection with the joy of reading.
My point is just that you can make that same connection using good books. If you take a little time and put together a library of great stuff, and you read to your child on a regular basis, and your child sees you and the other adults in the family reading on a regular basis for pleasure, and there aren't any hidden learning differences that impact a child's normal progression into being a competent reader, and if you make going to a library and a bookstore something that is fun and a treat, and if you let kids occasionally and within your budget spend money on books the way they do on other material things, you will guarantee yourself a child who has a lifelong love of reading. And you don't have to have a shelf full of Caldecott medal winners to do it, but why pass up something great and suffer through something mediocre instead???
